SPECIFICATION forming part of Letters Patent No. 511,625, dated December26, 1893.

Application filed May 10, 1893. Serial No. 473,663. (No model.)

To all whom it may concern.-

Be itknown that we, JOHN B. KENISON and MICHAEL F. BURK, of Lynn, countyof Essex, State of Massachusetts, have invented an Improvement inStaging-Brackets, of which the following description, in connection withthe accompanying drawings, is a specification, like letters and figureson the drawings representing like parts.

This invention has forits object to improve the construction of foldingstaging brackets, as well as means for securing the same to a building.

In accordance with this invention a wall plate and sole or support forthe stage boards, are pivotally connected together, and a two part braceis provided also pivotally connected together, the extremities of saidparts being pivotally connected to the wall and sole platesrespectively. A suitable locking device is provided for locking the twoparts of the brace in alignment in operative position. A rod having ascrew threaded outer end is secured to the bracket, as to the sole platefor instance, which is intended to project through the side of thebuilding, and an adjustable cleat is arranged on said rod, adapted tospan two of the usual studs or risers of the building, its adjustabilitypermitting it to span two studs or risers regardless of the particularpoint through which the rod projects, and a hand nut is turned on saidrod which binds the cleat firmly against the studs.

Figure 1, shows in side elevation a folding stage bracket embodying thisinvention; Fig. 2, a view showing the adjustable cleat; Fig. 3, a viewof the bracket, folded, and Fig. 4, an edge view of the locking devicefor the brace.

The wall plate CL, and sole 1) are arranged at right angles to eachother, and pivotally connected together at 2. A brace connects theextremities of the wall and sole plates, composed of two fiat metallicrods or bars 0, c, pivotally connected together at 3, the extremities ofsaid bars being pivotally connected with the wall and sole plates at 4.One of the parts as c has a notch 0 at one side which receives a stud cprojecting from the part c, and a thumb screw 0, passes through the partc, which enters a hole or socket in the part c. The end of the thumbscrew is upset, so that it cannot be readily removed from the part c. Alocking device is hence formed for the two parts or members of the bracerod.

A rod or bar d, is secured to the bracket, as to the sole plate forinstance, which projects rearwardly and passes through a slot in a cleatd, of suitable length to span or embrace two ordinary studs or risers ofa building. The outer extremity of this rod 01 is screw threaded andreceives upon it a hand nut d The bracket is applied to the exterior ofa building in process of construction, by projecting the rod cl throughthe boarding, regardless of the position of the studs or risers, thenmoving the cleat in one or the other direction as required so as toengage two studs, after which the hand nut (1 is turned, clamping theparts in position.

The advantage of providing an adjustable cleat is quite material as itenables the application of the cleat at any desired point on theexterior of the building without regard to the interior arrangement ofthe studs.

The brace rod is herein shown as folding inwardly when the bracket isfolded, but it is obvious that it may fold outwardly without materiallychanging the construction.

In a folding bracket, the wall plate a, sole plate I), pivotallyconnected therewith, a brace rod connecting the outer extremities ofsaid plates, and comprising two parts 0, a, pivotally connected togetherand to the plates, and a locking device for fastening the two parts ofthe brace rod securely together, substantially as described.

In testimony whereof we have signed our names to this specificationin.the presence of two subscribing witnesses.
